build: fix check_c_compiler_flag for -Wno-… (#10483)
`check_c_compiler_flag(-Wno-doesnotexist …)` is successful always,
apparently for all "no-" prefixes.
Therefore check for the flag itself (without "no-" prefix).
I am seeing a warning if the source fails to compile:
> cc1: warning: unrecognized command line option ‘-Wno-meh’
Which is turned into an error with `-Werror`:
> cc1: error: unrecognized command line option ‘-Wno-meh’ [-Werror]
But when it compiles successfully, there is no warning/error.
gcc (GCC) 9.1.0.
